Plectocomiopsis geminiflora – this is a palm that somehow didn’t get listed in our Flora. It’s really close to some of the species we have in Singapore especially the genera Plectocomia and Myrialepis, resembling the latter quite closely (maybe that’s why it got overlooked) yet distinct in some features like the disintegrating papery leaf sheath and the bristles on the midnerve which I use to pick out the rattan with in the forest. With the search image etched in mind, I am beginning to see more of this rattan around. See here for the article titled “Plectocomiopsis geminiflora (Griff.) Becc. (Arecaceae) — a new record for Singapore.” or download the pdf of the paper with the integrated corrigendum. (Thanks Siva).
